Description

Technical Field

[0001] This utility model relates to the field of refractory brick production and processing technology, and in particular to a cooling device for casting high zirconium bricks. Background Technology

[0002] Fused high-zirconium bricks are a type of high-performance refractory material. Due to their extremely high zirconium content, they possess excellent high-temperature performance, erosion resistance, and structural strength, and are widely used in critical parts of harsh industrial environments such as glass melting furnaces. The production of fused high-zirconium bricks mainly includes three core steps: electric arc furnace melting, casting, and annealing and cooling. Among these, the annealing and cooling process is one of the key factors determining product quality. If the cooling rate is not properly controlled, the temperature difference between the inside and outside of the brick will be too large, generating huge thermal stress, which can lead to cracks or even breakage of the brick, seriously affecting the product qualification rate and service life.

[0003] To prevent excessive heat loss during the annealing and cooling process of high-zirconium bricks, an insulated box is typically used, and the molds used for casting high-zirconium bricks are stored in a cooling box. The space between the enclosed cooling box and the mold allows for slow heat dissipation and insulation, thus ensuring the quality of the high-zirconium bricks. Existing refractory brick cooling technology discloses a Chinese utility model patent for a cooling and curing device for refractory brick preparation (Publication No.: CN217144320U), which includes a base with a feeding mechanism for conveying refractory bricks. Above the feeding mechanism is a cooling mechanism, which includes a protective box, an exhaust fan, and a water tank. The exhaust fan is installed on the side of the protective box, and the water tank is located on the upper surface of the protective box. An atomizer is installed inside the water tank, and a fan is installed on the upper surface of the water tank. A connecting pipe is installed on the fan, and a spray head is located at the end of the connecting pipe furthest from the fan. This utility model has a simple structure, reasonable design, and low production cost, greatly improving the cooling speed of refractory bricks while ensuring cooling uniformity and production quality.

[0004] The aforementioned existing technology for rapid cooling of traditional refractory bricks is obviously not suitable for the annealing cooling process of high zirconium bricks. However, modifying the cooling device of traditional refractory bricks would result in an overly complex device that would incur unnecessary costs for maintenance and repair. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a casting high zirconium brick cooling and insulation box that adjusts the heat preservation and heat dissipation states by adjusting the louvers of the box body.

[0006] This utility model is achieved through the following technical solution: a cooling and heat preservation box for fused high zirconium bricks, including a box body and a box cover, wherein the box body and the box cover constitute the external structure of an integral device, and heat dissipation holes with a hollow structure communicating with the inside and outside of the box body are evenly distributed on both sides of the box body, and a sealing strip is provided on the outside of the box body corresponding to the heat dissipation holes, and the sealing strip is slidably connected to a sliding rod.

[0007] To meet the requirement of slow cooling during the early cooling stage of high-zirconium bricks and improve the assurance effect of the device, an insulation structure is installed on the inside of the box and the box cover. The specific scheme is as follows: Preferably, a box insulation mechanism is provided on the inside of the box, and an upper insulation pad is provided below the box cover.

[0008] During the rapid cooling phase, to prevent the cabinet insulation mechanism from hindering heat exchange with the outside, the insulation material at the ventilation holes needs to be removable. The specific solution is as follows: Furthermore, the box insulation mechanism includes a lower insulation pad fixed to the bottom of the inner side of the box, two side insulation pads, and a fixed insulation pad fixed to the front and back of the inner side of the box. The distance between the fixed insulation pad and the inner side of the box is the same as the thickness of the side insulation pads. The side insulation pads are inserted between the fixed insulation pads and the side walls of the box.

[0009] Furthermore, an ear plate is provided above the side insulation pad, and a storage hole is provided on the upper insulation pad corresponding to the ear plate.

[0010] To improve the insulation and sealing effect of the device, the enclosure and cover need to be precisely positioned and assembled. The specific solution is as follows: Preferably, the upper edge of the box body is provided with a raised positioning block and a recessed positioning groove, and the lower part of the box cover is provided with a sealing groove and a sealing block corresponding to the positioning block and the positioning groove.

[0011] To facilitate the switching between heat preservation and heat dissipation modes of the device, the position of the sealing strip needs to be adjusted through simple operation. The specific solution is as follows: Preferably, the sides of the multiple parallel sealing strips on one side of the housing are fixed to the adjustment plate.

[0012] Furthermore, the adjustment plate is provided with two independent fixing holes distributed vertically, and the slide rod is provided with a positioning hole, into which a positioning pin is inserted.

[0013] To facilitate the use of the device, additional components for easy operation have been added, as detailed below: Preferably, a movable ear plate is provided above the box cover.

[0014] Furthermore, stacking holes are provided at the bottom of the box corresponding to the movable ear plate.

[0015] The beneficial effects of this invention are as follows: By adjusting and improving the traditional cooling and insulation box for casting high-zirconium bricks, this device utilizes a structure that allows for easy adjustment of heat dissipation and insulation effects. This enables rapid adjustment based on the temperature of the high-zirconium bricks during the annealing and cooling stage. Combined with the ability to quickly disassemble and adjust the insulation material inside the box, it ensures excellent insulation for the high-zirconium bricks when the temperature is above 600℃, and rapid ventilation and heat dissipation when the temperature drops below 600℃. This not only ensures precise temperature control during the annealing and cooling stage of the cast high-zirconium bricks, guaranteeing the quality of the finished product, but also greatly improves the production efficiency of high-zirconium bricks due to its ease of operation.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Example

[0024] like Figure 1-3 As shown, a cooling and insulation box for casting high zirconium bricks includes a box body 1 and a box cover 2. The box body 1 and the box cover 2 constitute the external structure of the overall device. The sealed structure formed by the box body 1 and the box cover 2 is the storage space for high zirconium bricks and molds. The internal space formed by the box body 1 and the box cover 2 is larger than the high zirconium brick mold, which can ensure that a certain gap is formed between the mold and the inner wall of the box body 1, thereby reducing heat loss and achieving the insulation effect for high zirconium bricks and molds. The two sides of the box body 1 are provided with evenly distributed heat dissipation holes 3 that are hollowed out and connected to the inside and outside of the box body 1. A sealing strip 4 is provided on the outside of the box body 1 corresponding to the heat dissipation holes 3. The sealing strip 4 is slidably connected to the slide rod 41. When the temperature of the high zirconium bricks drops below 600℃, the sealing strip 4 is moved and the box cover 2 is opened to realize the connection between the inside of the box body 1 and the outside space, thereby realizing the rapid cooling of high zirconium bricks and molds. This not only ensures the temperature control of the casting high zirconium bricks during the annealing and cooling stage and ensures the quality of the finished high zirconium bricks, but also makes the device easy to operate and can greatly improve the production efficiency of high zirconium bricks. Example

[0025] like Figure 2 and Figure 5 As shown, in order to meet the requirement of slow cooling in the early cooling stage of high zirconium bricks and improve the guarantee effect of the device, the device is equipped with a heat insulation structure on the inside of the box 1 and the box cover 2. The box 1 is equipped with a heat insulation mechanism, and the upper heat insulation pad 21 is installed under the box cover 2. The heat insulation structure inside the box 1 and the upper heat insulation pad 21 can better prevent the temperature change inside the device and effectively avoid heat loss during the slow cooling process.

[0026] During the rapid cooling phase, to prevent the insulation mechanism of the enclosure 1 from obstructing heat exchange with the outside, the insulation material at the heat dissipation hole 3 needs to be removable. The insulation mechanism of the enclosure 1 includes a lower insulation pad 11 fixed to the bottom of the inner side of the enclosure 1, two side insulation pads 5, and a fixed insulation pad 12 fixed to the front and back of the inner side of the enclosure 1. The distance between the fixed insulation pad 12 and the inner side of the enclosure 1 is the same as the thickness of the side insulation pad 5. The side insulation pad 5 is inserted between the fixed insulation pad 12 and the side wall of the enclosure 1. In this way, the side insulation pad 5 can be adjusted according to the heat dissipation requirements. When heat dissipation is needed, the side insulation pad 5 can be removed to ensure that the heat inside the device can be smoothly exchanged with the outside through the heat dissipation hole 3. When heat preservation is needed, the side insulation pad 5 can be inserted into the preset position. The operation is also very efficient and convenient.

[0027] An mounting ear plate 51 is provided on the upper part of the side insulation pad 5, and a storage hole 22 is provided on the upper insulation pad 21 corresponding to the mounting ear plate 51. Through the mounting ear plate 51, the operator can use tools to install and remove the side insulation pad 5.

[0028] The lower insulation pad 11, the fixed insulation pad 12, the upper insulation pad 21, and the side insulation pad 5 are all made of high-temperature resistant materials with a loose internal structure, such as foamed ceramics. Example

[0029] like Figure 1-3 As shown, in order to improve the heat preservation and sealing effect of the device, the box body 1 and the box cover 2 need to be precisely positioned and combined. The upper edge of the box body 1 is provided with a raised positioning block 13 and a recessed positioning groove 14 respectively. The bottom of the box cover 2 is provided with a sealing groove 23 and a sealing block 24 corresponding to the positioning block 13 and the positioning groove 14 respectively. Since the use of the device requires the box cover 2 to be opened and closed frequently, and the sealing degree of the box cover 2 and the box body 1 is directly related to the heat preservation effect of the device, the corresponding cooperation design of the positioning block 13 and the positioning groove 14 with the sealing groove 23 and the sealing block 24 can not only ensure the accurate placement of the box cover 2, but also increase the sealing performance of the box body 1 and the box cover 2 in the closed state, thereby ensuring the reliability of the device. Example

[0030] like Figure 4 As shown, in order to facilitate the switching between the heat preservation state and the heat dissipation state of the device, the position of the sealing strip 4 needs to be adjusted by simple operation. The sides of the multiple parallel sealing strips 4 on one side of the housing 1 are fixed to the adjustment plate 42. The adjustment plate 42 is provided with two independent fixing holes 43 distributed vertically. The slide rod 41 is provided with a positioning hole 44. The positioning pin 45 is inserted into the fixing hole 43 and the positioning hole 44. The operator can adjust the position of all sealing strips 4 on one side by moving a single sealing strip 4. At the same time, by inserting the positioning pin 45 through and into the corresponding fixing hole 43 and positioning hole 44, the opening and closing of the heat dissipation hole 3 of the device can be adjusted. Example

[0031] like Figure 1-5 As shown, for ease of use of the device and to accommodate the need for cooling and stacking in large-scale production processes, a movable ear plate 6 is provided above the box cover 2, which allows operators to adjust the box cover 2 using lifting equipment. At the same time, a stacking hole 61 is provided at the bottom of the box body 1 corresponding to the movable ear plate 6, which facilitates the stable storage of each independent device when the entire device is cooled and stacked. The upper device can be placed on the movable ear plate 6 of the lower device through the stacking hole 61, ensuring stable stacking and neat stacking, and avoiding waste of storage space.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
